I have taken a series of HDR shots today using my 1D X and 24-105L lens. I have also used a tripod and the camera is set to auto bracketing (5 exposures). In just about every series of shots the very first picture has camera shake and the other 4 exposures are sharp. I was wondering if anyone else had this problem before and if it is possibly the Image Stabalizing motor causing the shake? What is strange is that it is for instance a 3 sec exposure that is shaky but the longer exposures are perfect... This is very confusing!

Do you press shutter release button for the first picture to be taken?

Uhhh.... Isn't the shutter release button supposed to be pressed? Sorry I know what you mean and I am not using a cable release, but I press the button exactly the same way with all 5 exposures and it is always only the first exposure that shows camera shake. I will experiment a bit more but I do recall I had some issues with sharpness before using the camera on a tripod with IS switched on.

1- Do not use the IS when on tripod2- Use shutter release with a delay (2 seconds or 10 seconds )

let us know how it goeshave a good one.

It is indeed the Image Stabalizing! I tested some more images today and when the image stabalising is switched off, the first frame is fine, but when it is on, I get camera shake... I know this sounds like exactly the opposite of what should be working, but it seems the IS doesn't like it when the lens is beign held still by a tripod

It also looks like it is happening more in the f18-f22 range and when the camera is slightly tilted upwards. Looks like the Image Stabalizer kicks in for a second to see if it should stabalise and the vibrations causes the camera shake.

For my humble TI1, I use mirror lockup + tripod + remote shutter or 2s timer shutter release to make everything as stable as possible when doing long shutter photography. I also use my heavier tripod for this. I don't know if I can teach you much because I'm just a rebel user.
